HI-4852PSTF

Overview

The HI-4852PSTF is a half-duplex RS-485 transceiver manufactured by Holt Integrated Circuits Inc. It provides one driver and one receiver for balanced data transmission. The device operates from a single 3.3V supply voltage and features differential input and output signal types. It is designed for industrial applications with an operating temperature range of -40°C to 85°C. The component utilizes CMOS process technology and is housed in a surface-mount package.

Feature Summary

• Supports RS-485 standard for robust noise immunity in noisy environments
• Integrates on-chip protection against electrostatic discharge and bus faults
• Enables high-speed data communication over twisted-pair cables

Applications

• Industrial automation control systems
• Building automation networks
• Factory floor sensor interfaces

Procurement Notes

Verify the specific suffix PSTF against the manufacturer's current datasheet to confirm pinout and package dimensions. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies. Ensure the single 3.3V supply requirement matches the target system design constraints before ordering.

Selection Notes

Select this component when a half-duplex RS-485 interface is required for industrial-grade reliability. It is suitable for designs needing a single-supply operation at 3.3V. Compare its fault protection levels and data rate capabilities against other RS-485 transceivers if higher speed or full-duplex functionality is needed.
